UNITED STATES PATENT OFFICE.

HENRY 0. WAY, OF THORN TOWN, INDIANA.

IMPROVEMENT lN FLOOD-GATES.

Specification forming part of Letters Patent No. 116,247, dated J une20, 1871; antedated J une 15, 1871.

Be it known that I, HENRY 0. WAY, of Thorntown, in the county of Boone and State of Indiana, have invented anew and useful Improvement in Flood-Grates and I do declare that the following is a true and accurate description thereof, reference being had to the accompanying drawing and to the letters of reference marked thereon and being a part of this specification, in which- Figure l is a perspective of the front, looking down stream and Fig. 2 is a similar view of the rear, looking up stream.

Like letters indicate like parts in each figure.

The nature of this invention relates to the construction of a flood-gate to be erected over streams, so arranged that it will open at the pressure of the water, drift-wood, &c., and close when the pressure is removed, without danger of being carried away. The invention consists in the peculiar arrangement of the various parts for the purpose, as more fully hereinafter described.

In the drawing which accompanies this specification and forms a part thereof- A represents posts firmly driven into the bank upon either side of the stream. B are two gates hung by suitable pintles O to the posts in such a manner that when said gates are closed they will stand at an angle with each other, the point of the angle being the outer ends of the gates and pointing down stream. I call the inner ends of the gates the ends which are pivoted to the posts. D areheavy iron or steel springs, so arranged upon the down-stream side of the gates as to compel them to close when relieved from pressure from the opposite side. E are beveled fenders secured to the up-stream side of the posts to compel drift-wood and other obstructions to glide toward the center, where the two gates meet, and to protect the posts. When the pressure from above becomes too great the gates open and the obstructions pass through theopening, when the springs compel the gates to close.

What I claim as myinvention, and desire to secure by Letters Patent, is

A flood-gate wherein the posts A, gates B, pintles O, springs D, and fenders E are constructed, arranged, and operatin g substantially as and for the purposes set forth.

HENRY 0. WAY.
